Who this suits and who should look elsewhere

Owners of the listed Sony models needing a direct 100% OEM-compatible replacement will find this cell matches the original voltage and form factor. Buyers whose headset uses a different battery connector or voltage requirement should look elsewhere.

Critical specification: 3.7V 350mAh Li-Polymer

The single figure that decides fit is the 3.7V 350mAh lithium-polymer rating, which must match the original cell exactly. Physical dimensions are 34.88 x 20.10 x 7.00 mm, so the battery compartment must accept this size.
